HOSE-PIPE COUPLING.

Patented Mayl, 1918:

Application 1ed-Ap1'i129, 1916. Serial' No. 94,286.

To all r'wiz/0m t may concern;

Beit knownthatl, WILL RI PORTER, a citizen ofthe United States, and a resident of Prince-Bay, in thek county of Richmond, .State of New York, Ahave invented certain` new and useful1 Improvements in Hose-Pipe Couplings, of which thef following ,is a specification, reference being had 'to the accompanying. drawings.

My invention relates particularlyv to the connection between aiiexihle tuberor hose and fa device for 'controllingor distributing the iuid conveyed through said hose, and is especiallyV directed to the means for binding the hose to the nipple of suchadevice.

The principal object-s of my invention are, to provide such. a connection with means for binding the tube upon the nipple with such uniform `force lasi-to inieifect form a composite substantially integral structure incapable of accidental separation or leakage. y

Other objects of my invention are to provide a hose pipe connection wherein the tube or hose may be conveniently engaged with the nipple and readily removed therefrom without injury to any of the parts forming said connection.

Specifically stated, the form of my invention herein described provides a hose orl tube of rubber engaged with a nipple and embraced 'by a yielding collar, which is forced into binding engagement with said hose by an internally threaded ferrule having its threads arranged to engage said collar.

My invention'further includes all of the various novel features of construction and arrangement as hereinafter more definitely specied.

In the accompanying drawings, Figure 1 is a side elevational view of a valve to which a hose is connected in accordance with my invention, said hose and its attaching means being shown in section for convenience of illustration; Fig. 2 is a perspective view of the ferrule shown in Fig. 1; and F ig. 3 is a side elevational view of a T-fitting, having a hose connectlon shown in section and embodying a modification of my invention.

In said igures, the valve body 4 is provided with the laterally extending hollow with the collar 10 so as to tightly bind it upon the hose between the valve body l and' the shoulder 7, thereby preventing the accidental longitudinal movement of said hose upon the nipple-5.' Said ferrule 12 is provided with a knurled band 15, as best shown in Fig. .2, by which it mayr be conveniently rotated between the thumb and finger of the operator.

It may be here noted that it has been found in practice that the best results may be obtained wherein the exterior strands forming the collar 10 are helically coiled away from the bound end of the hose 9 and terminate adjacent to the shoulder 7 It will be obvious that when the ferrule 12 has its threads 13 Aengaged with the collar 10 and its end abutted against the valve body 4, further rotation of said f errule will naturally tend to force the collar back away from the valve body t, which will also tend to carry that portion of the hose 9 between the valve body and the shoulder 7 longitudinally against said shoulder with such force as to render impossible the accidental displacement of said hose from the nipple 5 or any leakage between the hose and said nipple.

In the form of my invention shown in Fig. 3, the T-tting body 17 is provided with the laterally extending hollow nipple 18 having the tapered portion 19 which provides a shoulder 2O serving to retain the hose 21, which may be slipped over said nipple and embraced by an annular collar 22 formed of pliant material such as felt, rubber, leather, lead, or in fact any material into which threads may be formed by the rotative engagement of the ferrule 25 having the threads 26 therewith.

I do not desire to limit my invention to u the precise details of construction and arrangement herein specied as itis obvious that various modifications may be made therein without depart-ing from the essential. `features of my invention as defined in the appended claims. v

Having thus' described my invention, I claim:

l. A coupling for connecting a' hose a hollow nipple over which the end of said hose may be slipped, comprising a collar formed of strands of suitable material wrapped about ysaid hose, yand a errule having screw-threads arranged to engage said collar, and form threads therein. n

2. A coupling for connecting a hose to a hollow nipple over which the end ofosaid hose may be slipped, comprising a lcollar Copies of this patent may be obtained. for

relation therewith, and bind said callar thereon..V Y v M i 4. A coupling for connecting a hose to a hollow nipple having a shoulder, over which the end of said hose maybe slipped, f comprising a collar formed of strands of suitable material helically wrapped about said hose in proximity to said shoulder, and a ferrule having'` screw-threads arranged toy engage said collar thus formed, in threaded relation therewith.

5. A 'coupling `for connecting ahose to a fluid controlling or distributing device, having a hollow nipple provided with 'a shoulder, over which the end of said hose 4f may bev slipped, comprising a collar formed ofk strands of' suitable material wrapped about said hose between its end andsaid shoulder, and a ferrule rotatably einbracing said hosei and having .screw-threads arso ranged lto engageV said collar in thread'- ed relation therewith, irrespectivew'of'. said strands. v l In witness whereof, I have hereunto set my hand this thday of April, A. D., 1916. 55
